Reorganizing a bathroom can be a pretty major project, so do one bathroom at a time, starting with the most used bathroom in your home. Divide up the bathroom into sections (countertops, cabinets, shelves, shower, closet, and so on).

Begin with the basics: toiletries. Most people have a cumbersome collection of toiletries that they just don't use. Perhaps you purchased an expensive shampoo a year ago that did not work for your hair, but guilt has caused you to hold on to it. If it doesn't work for you, clear it out!

You might have a friend or neighbor who could enjoy the product. Offer it to them. If they turn you down, drop it into the garbage. If you live in a city with alleys, you might place these items in a box beside your dumpster. Somebody might actually come by and choose to take your half-used bottles.

An artful display of toiletries.

There comes a time in the life of every tube of toothpaste when you just can't squeeze any more out of it. You twist and prod and poke, knowing there is at least a few good drops left in there, but they won't come out. Now is not the time for guilt or shame. Just toss those abused tubes into the garbage. Tomorrow morning, you'll be glad to have just one full tube available to you, instead of several mostly used tubes. Your energy is better spent decluttering than agonizing over a few drops of toothpaste.

Although a few old toothbrushes can be kept on hand for cleaning grout and other hard-to-reach places, don't hold on to too many, as they probably won't get used all that frequently. Cleaning with toothbrushes is just a little bit too labor intensive to do it on any kind of a regular basis. Also, make sure that you clearly mark old toothbrushes that you plan to use for cleaning with a permanent marker.

As you shop for toiletries, try to practice no-net-gain. If you buy a new bottle of shampoo, throw out a mostly used old one. If you buy a new tube of toothpaste, get rid of the tubes you're not using. Ideally, every time you place something new in your cabinet, you'll take something out, so that you're not increasing the bathroom bulk each time you shop. Also, the less you keep in your bathroom cabinet, the better. While you'll need room for essentials, a disorganized cabinet can cause you to purchase items that you already have. You want to be able to open the cabinet door and quickly assess both what you have and what you need.

Thoroughly purge just one section at a time. Be aware that you might be tempted to tackle more than you can in the limited time that you have, and resist the temptation to immediately empty every closet and cabinet. If the project becomes too big too fast, it can quickly become overwhelming and unmanageable. As the FlyLady says, “Never take out more than you can put back.”
